sufficient. Even after a man, A, for example, offers purchasing power, he will not get a piano unless there exists an accumulation of unemployed capital, together with labor ready to manufacture the instrument. If capital were all previously occupied, no piano could be made, although A stood offering an equivalent in valuable goods. It may be said that A himself has the means. He has the wealth, and if he is willing to forego the use of this wealth, or, in other words, save it by devoting it to reproduction in the piano industry—that is, create the capital necessary for the purpose—then the piano can be made. But this shows again that, not a mere desire, but the existence of capital, is necessary to the production, and so to the employment of labor. An increased demand for commodities, therefore, does not give additional employment to labor, unless there be capital to support the labor.
Some important corollaries result from this proposition: (a.) When a country by legislation creates a home demand for commodities, that does not of itself give additional employment to labor. If the goods had before been purchased abroad, under free discretion, then if produced at home they must require more capital and labor, or they would not have been brought from foreign countries. If produced at home, it would require, to purchase them, more of what was formerly sent abroad; or some must do without. The legislation can not, ipso facto, create capital, and only by an increase of capital can more employment result. It is possible, however, that legislation might cause a more effective use of existing capital; but that must be a question of fact, to be settled by circumstances [pg 092] in each particular case. It is not a thing to be governed by principles.
